Today is Carl Sagan's birthday. He would have been 75 years old today. In celebration, here are two music videos that use clips from his epic documentary Cosmos.
These were made using software called "Autotune." Normally, Autotune is used to correct singers who sing a little off key. You can see how Autotune works here. This is a pretty creative use of Autotune, using it to take normal speech and convert it into songs. Some people have done it with news stories as well (check out our favorite example).
